My radiator cooling fan is wobbly. I could hear slight knock when my jeep was idling, i checked it out and found that my fan has some play to it like 1/2"-3/4" from center.
Is it the entire fan assembly i need to replace or is there a bearing that is pressed into the assembly that i can replace. Also I havent looked into it too much but i dont even know how to take the fan off....
Thanks for any info, i'm not sure even what i need
Yeah if there is play at the shaft going in to the water pump then the pump will need replaced. It's not very likely that the fan part itself would be loose but there are bolts there as well you can check.

The output shaft its self is rock solid! its not the water pump.
The actual clutch housing is whats wobbling on the shaft. Its not loose bolts or loose fan blades. Its excessive play in the clutch assembly on the shaft (front to back motion). As if a bearing or something was shot.
"To test whether or not your fan clutch needs to be replaced, simply spin your Jeep's fan by hand while the engine is cold and if it spins freely 5 rotations or more, it will need to be replaced. Fortunately, this is a very easy task to do but like any job, the right tools can make all the difference. "

My fan clutch went out about a year ago . . . luckily it was covered under warranty so I'm not sure how much it'll set you back. I had a squeeling noise and had it in to the dealership 3-4 different times . . . they tried replacing the idle pulley, belt tensioner, nothing helped . . . so me and a buddy poked around under the hood and noticed the you could grab one of the fan blades and move it forward and backward . . . took it back to the dealership and got a new fan clutch and haven't had the issue since. Good luck . . . hope it doesn't set you back too much.
